Kemira's expertise in water chemistry and water treatment was recently used by a nickel refinery struggling with its wastewater treatment. As a key supplier to the refinery, Kemira was asked to investigate and develop alternative treatment methods to ensure compliance with regulatory demands. From NSF NSF/ANSI Standard 53: Drinking Water Treatment Units - Health Effects Overview: Standard 53 addresses point-of-use (POU) and point-of-entry (POE) systems designed to reduce specific health-related contaminants, such as Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs), MTBE (methyl tertiary-butyl ether), that may be present in public or private drinking water.

Analytical Method: Nickel in mineral water

In water containing large amounts of hardening constituents, after the addition of all reagents of the test sets, a turbidity occurs. This can be dissolved with the addition of about 20 mg tri-sodium citrate dihydrate without disturbing the detection of nickel.

Copper, nickel, zinc, manganese etc. are co-precipitated in Fe oxides and cobalt, iron, nickel and zinc are co-precipitated in manganese oxides (Stumm and Morgan, 1981; Noller et al., 1994). Even though chemical precipitation is a widely used method, it has the drawbacks of producing large amount of concentrated and further toxic sludge wastes, which leads to disposal problems.

Nickel allergy

Once a nickel allergy is detected, the best treatment is avoidance of nickel-releasing items. The top 13 categories that contain nickel include beauty accessories, eyeglasses, money, cigarettes, clothes, kitchen and , electronics and office equipment, metal utensils, aliment, jewelry, batteries, orthodontic and dental appliances, and medical equipment. [35]

Wastewater discharged to surface water without a proper control can pollute rivers and lakes, and even ground water. To protect water in the US from pollution by discharged wastewater, the Clean Water Act (CWA) was established in 1972 as amendments to and replacement of the Federal Water Pollution Control Act of 1948.

The water undergoes a thorough water treatment process and then is distributed by traditional water mains. The type of pipe used in most water mains is copper pipe or galvanized pipe. Copper pipeline probably doesn't contain any nickel, whereas nickel is abundant in the zinc coated steel or iron made galvanized pipes.

Treatments of cadmium-cyanide and nickel-cyanide electroplating rinse water were investigated in an electrochemical reactor equipped with iron plate electrodes in a batch mode by electrocoagulation (EC). Effects of the process variables such as pH, current
